1990-2020年云南省30米LULC分类数据集(第一版)
收藏资源简介:
该数据集为云南省1990-2020年的土地利用/土地覆盖数据,含4个子数据。数据均通过Google earth engine平台中的随机森林分类器生产。在生产过程中,所有的流程都被严格地监督和执行,比如高质量影像数据合成、样本点筛选、精度评价等。数据的平均总体精度大于85%,具有一定可靠性。数据可为后续的土地利用/土地覆盖变化研究提供基础;同时,可为云南省的土地资源管理、自然资源调查以及环境监测等提供数据基础。
This dataset comprises land use/land cover data of Yunnan Province from 1990 to 2020, including 4 sub-datasets. All data were generated via the random forest classifier on the Google Earth Engine (GEE) platform. During the generation process, all workflows were strictly supervised and executed, including high-quality image synthesis, sample point screening, accuracy assessment and other relevant procedures. The average overall accuracy of the dataset exceeds 85%, demonstrating considerable reliability. This dataset can serve as a foundational resource for subsequent research on land use/land cover change, as well as provide data support for land resource management, natural resource surveys and environmental monitoring in Yunnan Province.
